The 160th SOAR (Special Operations Aviation Regiment, also known as the Night Stalkers) recently held exercises in New York City, to the consternation of some residents who, after 9/11, aren't comfortable having aircraft fly past their windows at halitosis range.
Some of their pilots took advantage of the opportunity to show those near the river what they can do.
I doubt very much that was in the operations plan, but I bet they enjoyed it . . . and I'm sure they used the excuse of "But it's an important exercise!" to get away with it. Boys in uniform are still boys at heart. You ask me how I know this? Trust me. I know this. Been there, done that, and got several dozen T-shirts (and not a few scars) to prove it.
